Ok ... what I though was a compiler bug may actually be a bug in 
sparc/include/profile.h...If I back out the following change, it works:

...though, asking Charles about it, his comment was:

	"Still not clear whether that's a bug in profile.h or not."

In any case, Paul probably had some reason for making that change, but 
for now, at least you can compile your C library...
